OPENAI LAUNCHES APPS INSIDE OF CHATGPT

ChatGPT users can now access interactive applications from companies like Booking.com, Spotify, Figma, and Canva right inside the conversation. OpenAI is trying to build an ecosystem of apps that can be launched directly in ChatGPT's responses, letting users call up third-party tools in their conversations. It has launched a preview of its Apps SDK for developers to start building apps. OpenAI says the new system is built using the Model Context Protocol, which allows developers to connect data sources to AI systems.

TYPESCRIPT VS ZOD: CLEARING UP VALIDATION CONFUSION

TypeScript and Zod serve complementary rather than competing roles in development. TypeScript provides compile-time type safety during development and building, while Zod validates untrusted data at runtime. This is very useful for external inputs like API requests, user forms, and third-party data.

US-based funds led with $5 billion, followed by record weeks for Switzerland ($563M) and Germany ($312M).

DISCOVERY OF CELLS THAT KEEP IMMUNE RESPONSES IN CHECK WINS MEDICINE NOBEL PRIZE

Mary Brunkow, Fred Ramsdell, and Shimon Sakaguchi were awarded the 2025 Nobel Prize in Physiology or Medicine for their work in the discovery of specialized immune cells that keep potentially harmful immune responses in check. These regulatory T cells play a key role in peripheral immune tolerance, a non-central process that allows the immune system to balance its response. The discovery has opened up new lines of research into peripheral immune tolerance. Researchers are now working on manipulating T cells so that they can't protect cancerous tumors, engineering them to treat autoimmune diseases, and recruiting them to protect transplanted organs and tissues.
